Highly accurate diamond appraiser

One reason you can expect the best prices for your diamonds is because of the accurateness of your diamond appraisal.  State-of-the-art equipment known as a SARIN proportion analyzer gives a highly accurate appraisal that is well beyond basic diamond certification. 

Certified diamonds

Typically, diamonds are submitted to an independent laboratory for grading. The lab then does a report with details of the weight, size, clarity and color of a diamond.  The report also details the polish, symmetry, and proportions of a diamond.

In America, the best-known laboratories are HRD Antwerp, the Gemological Institute of America, the European Gemological Institute, the American Gemological Society and the International Gemological Institute. 

If you used one of these labs as your diamond appraiser, simply scan your grading report and email or fax it to Ralph Mueller & Associates. You will be  given an estimate of how much we would pay for it. We will give you a precise price offer once we get the chance to inspect it. We do not charge for evaluations and you are not obligated to sell to us because we have evaluated your diamonds.
